GLASS-CUTTING FRAME.

Specification of Letters Patent.

Patented Nev. a, 1920.

Application filed February 211, 1919. Serial No.A 278,756.

To all fw 7mm t may concern Be it known that I, FRANK C. RnMsBEnG, a citizen of the United States, residing at Santa Ana, in the county of Grange and State of California, have invented new and useful Improvements in Glass- Cutting Frames, of which the following is a specifcation.

It is common practice among glaziers to use a table covered with a fabric, and having scales on the left hand and lower edges, for the support of glass panes, when cutting the latter. My invention relates to a frame serving as a table for like purposes.

It is an object of this invention to provide an open spaced frame, which will serve as a means for setting and alining the straight edge for guiding the glass cutter and the glass panes to be out. ,Another object of this invention is to provide a frame of the character described with adjustable stops of a novel character adapted for abutment by the pane or straight edge.

In addition to the broader features of this invention, there are certain details of construction, whereby a simple, convenient frame, light in weight is obtained, and whereby a structure having a certain amount of resiliency and flexibility so as to conform to the surface of a glass pane, may be se cured.

I accomplish the above mentioned objects by means of the embodiment of my invention illustrated in the accompanying drawin in which:

Figure 1 is a plan view of a complete frame with two adjustable stops thereon and the straight edge disposed upon the frame, some of the scale markings being omitted. Fig. 2 is a bottom view of the straight edge drawn to a reduced scale. Fig. 3 is an end view on an enlarged scale of the straight edge. Fig. 4E is an elevation on an enlarged scale of the bottom right hand border piece of the frame with one of my adjustable stops mounted thereon. Fig. 5 is a section taken on the line 5-5 'of Fig. 4. Fig. 6 is a detail view of the foldable stop mounted on a side border piece. Y

Fig. 7 is a fragmentary plan view on an enlarged scale illustrating the bottom right hand corner of the table.

The table is of a general checker board form having border pieces 8, 9, 10 and 1l. The top and bottom border pieces 8 and 10 are marked with scales reading from left to right and divided according to some standard unit of measurement, inches for illustration. The side border pieces, 9 and 11 are similarly marked with scales reading` from the bottom to the top. Bridging the side pieces are slats l2 spaced at uniform intervals, lIhe upper surfaces of the slats are in the same plane as the upper surfaces of the side pieces. Bridging the top and bottom border pieces are slats 13, which are uniformly spaced and have their upper surfaces in the same common plane. All of the slats 12 are marked with scales corresponding to the scales on the top and bottom border pieces. In a like manner, all of the slats 13 are marked with scales corresponding to the scales on the side border pieces. The slats 12 and 13 are notched to receive each other at their intersections to t provide a flat upper surface upon which the glass may be laid. This construction provides a frame which under pressure can be somewhat warped so that a glass pane laid thereon will not bend and warp under pressure, but rather the frame will bend to conform to the surface of the glass, and thereby prevent cracking of the latter.

Upon the side border pieces of the frame are foldable stops indicated by 111 and 15. .ihese stops are located adjacent the bottom border piece andere duplicates of each other. One will be described. Referring particularly to Figs. 4E and 6, a butt bracket 16 has pivotecl therein an arm 17, so that when folded, as shown in dotted lines, the arm will be below the upper surface of the frame, and when opened the arm will eX- tend above the upper surface of the frame and beheld against movement in one direch tion to the right in Fig. 6 (further opening movement) by the arm throwing against the back of the bracket 16. l

Referring particularly to Fig. l, adjustable stops are indicated by 18. There are two shown herein, but several may be used as found convenient, and as they are duplicates of each other, only one will be de scribed. Referring particularly to Figs. 4 and 5, a stop is comprised of a slide block V19. A. notch 20 is cut upon the lower face of the slide block for the reception of a bolt 21, so that the latter will clear the surface upon which the block rests. On the upper surface of the block adjacent the edges are grooves 22 and 28, in which are hooked clamps 24 and 25. The bolt 21 eX- tends through alined holes in the clamps 24 and 25. Upon the threaded end of the bolt is a thumb nut 26. When the adjustable stop is disposed upon one of the border pieces or slats, and the thumb nut loosened, the slide block may be adjusted to entend more to one side than the other of the clamps, as desired. By tightening the thumb nut 26 the stop is clamped to the border piece or Slat, and the slide block is clamped in fixed position with respect to the clamp.

.The straight edge is of the usual form, but provided with a bracket 28. T his bracket is intended to be hooked over the outside edge of a border piece and is convenient in locating and holding one end of the straight edge in its proper position while the other end is being located and held. For instance, the operator hooks the bracket 28 over the edge of the frame farthest from him and thus can hold that far end of the straight edgein ixed position while he locates the end he holds in his hand. rllhe stops 111 and 15 are so positioned that when opened and the straight edge abuts thereagainst, the lower edge of the straight edge will be disposed above the lower edge of the frame a distance equal to that which the cutter will extend beyond the straight edge. By moving the cutter along the straight edge in this positi on,.a cut will be made which coincides with the lower edge of the frame. (l mean by the lower edge the edge normally closest to the workman and which, in the drawings, is the edge 10.)

Suppose a pane of glass is to be cut of, the dimensions, say, 12 X 241 inches, and that the stock is rectangular adjustable stops 18 are placed as shown in Fig. 1 with the lower faces of the slide blocks registering with the marks 'on the slat and side piece numbered 12. rfhe stops 14 and 15 are then raised to the positicn shown in Fig. 6. The upper edge of the stock pane is butted against the stops 13 and the left hand edge against the stopV la. IThe straight edge is then placed below stops 14: and 15 so that it butts against the latter, and the cutter drawn along the lower edge of the straight edge, thereby making a-cut 12 inches from the upper edge of the pane. The straight edge is then lifted and the bracket end hooked over the top piece with the right hand edge disposed about in registry with the mark 24: on the top piece. However, enough clearance is left between the mark and the right hand edge of the straight edge to compensate for the clearance of the cut ter. The Vfriction of the bracket 28 against the top piece will prevent the straight edge from becoming displaced from its position at the top ofthe frame. VThe bottom end of the straight edge is then swung into a position on the bottom piece corresponding to its pesition on the top piece. Another cut is then made aterlght angles to the first cut, and 211 inches from the left hand edge of the pane. .lfa number of the panes are to be cut of the same size, then more of the adjustable stops may be placed upon the slats 12 in proper position for the straight edge te abut against them with the cutter edge in position for .the dimensions to be cut. 1n trimming edges, it'will be found convenient to move the slide block ofthe adjustable Vstop so that the thumb nut will clear the edge of the stock. Again, when the clamps are to be attached close to slats at right angles, the slide block may be moved in the clamp to dispose its end at the proper position. rlhere are various other uses for the adjustable blocks which will be apparent yto a glazier making use of the frame; but these uses are so numerous in detail, that it issuperfluous for me to attempt to describe them here.
